Abstract
Fermentations of glucose in the presence of carbon dioxide-C14 were carried out with strains of Actinomyces under aerobic and anaerobic conditions and with Lactobacillus bifidus. Succinic acid formed by these organisms has a high percentage of its radioactivity in the methylene carbons. When one strain of Actinomyces was grown in the presence of oxygen, 90% of the total radioactivity of the succinic acid was found in the methylene carbons as compared to 62% when it was grown anaerobically. Differences between the fermentations of glucose by the genera Actinomyces, Lactobacillus, Propionibacterium, and Corynebacterium are emphasized.
